In the accompanying drawings, in which The Upper eompflltment-18 SGThVeS21S the is shown one of various possible illustrative geSifiCe-tionChamber and 1S S1II111eI1y proembodiments of this invention, vided withthe opening 25 from which ex- Fig. 1 is a vertical section of ahydrocartends the outlet pipe 26 for leading the gasi- 915l bon burner,embodying this invention, tdisfied oil into the valve chamber 27, fromwhich it emerges through the valve opening 28 into the furnace box 10.The supply of gasified oil is controlled by means of the needle valve29. The latter comprises the usual valve stem 30 having a hand wheel 31at the extremity thereof and a valve head 32 operatively disposedadjacent the valve opening 28. Means are provided for injecting steam orcompressed air for aiding in atomizing the gasified oil. For thispurpose a valve 33 is inserted in the supply line 34 for the steam orcompressed air. The valve 33 is of the usual construction having thevalve head 35, and the lia-'nd wheel 36. Below the valve 33, an annularchamber 37 is provided disposed adjacent the lower end 38 of the supplyline 34 for receiving the steam or compressed air. The latter is thenled through small openings or channels 39 around the valve chamber 27leading through the opening 40 by means of the channels 41, so that anintimate mixture of the gasified oil and steam or compressed air isobtained upon emerging from the outlets 28 and 40. Before entering thefurnace the atomized gas and steam, or compressed air enter the circularmixing chamber 42 where an intimate mixing of the gasified oil andcompressed air or steam is obtained, and the A gasified oil is thenfurther atomized so as to produce a highly efficient combustiblemixture, which will burn without smoke. Orifices 43 for'admitting airfrom the outside are provided in the mixing chamber for starting theburner when no steam or air under pressure has -yet been admitted. Thesupply of air may be regulated in any suitable manner, during continuedoperation of the burner as by means of a ring or sleeve 44 having ports44a which ring may be operated to close or open the orifices 43thus-securing proper combustion at all times.

It is clear that part of the heat of combustion, generated in thefurnace, serves to heat up the distillation and gasification tube 16,particularly by reverberation through the passage 15. For effectivelyand positively controlling the temperature to which the oil is subjectedduring distillation and gasification, I provide the dampers 45, 46,disposed horizontally over the tube 16 between the latter and thepassage 15. The dampers may be of any suitable design, preferablyarcuate in cross-section, as shown in the drawing, and when spaced'fromeach other as shown in Fig. 2 to provide a variable opening 47wheret-hrough heat from the furnace box is transmitted to or impinged onthe distillation and gasification tube 16. The said dampers 45, 46extend respectively from the upper ends -of the arms 48, 49, which aresecured at their opposite ends respectively to the rock shafts 52, 53,having the operative handles 54, 55. The dempers 45, 46 may be movedtoward or away from each other by rotating the rock shaft 52, 53, thusvarying the size of the opening 47, and regulating the heating of thetube 16, as will be readily understood.

For. starting the hydrocarbon burner, I provide the trough or basin 56disposed belowthe distillation and gasification tube 16 and adapted tocontain a. suitable liquid fuel such as alcohol which is burned tosupply the initial heat for raising the tube 16 to the requiredtemperature for distilling and gasifying the oil.

The operation of the device will now be clear. The hydrocarbon oil isfed through theinlet 23 into the distillation and gasification tube 1'6,where it is heated to the required temperature. In the lower compartment17. the oil is distilled so that volatile combustible ingredients oflower boiling points are separated from those of the higher boilingpoint oils, thus eliminating to a large degree the smoke producingelements. From the distillation compartment 17, the distillate passesthrough the passage 20 into the gasification compartment 18 and theninto the atomizing chamber 42 through the valve 29 which regulates thesupply of gaseous fuel to the furnace box. The steam or compressed airline is opened shortly after the burner has warmed up and as alreadyexplained is intimately mixed with the gaseous fuel before entering thefurnace box. At the start the air orifices 43 are adjusted by means ofthe ring 44 for supplying the initial air to the furnace. After theburner has been started, the outside air supply may be shut off orregulated to obtain the greatestheating effect. The dampers 45, 46 arealso adjusted to provide the desired size of opening 47 for the radiantheat from the furnace box to the distillation and gasification chamberso as to obtain the maximum heating effect.

vIn Fig. 4 of the drawing a modified form of the burner is shown wherebythe. oil inlet portion of the burner may readily be disassembled anddismounted. In this form the distillation and gasification tube 16 is aseparate member which may be inserted through an opening in thesupporting frame 12. The inlet 23, outlet 26, and exhaust 24" are all inone piece or casting 56. which may be detachably mounted in operativerelation to the tube 16a. In the particular form shown in Fig. 4, thistube is provided with a flange 57 which is mitered as at 57a to form aseat for the correspondingly mitered member 58 of the piece- 56. A lug59 extends from the frame 12a and a screw bolt 60 extends through saidlug with its head abutting against the piece 56 to secure it inposition. The baffle plate 19 is secured atone endto the head of thepiece 56 and extends into the tube 16a so that when the piece 56 isremoved, the balile is withdrawn together therewith.
